🔭 Azure Analytics Services Overview

Comparative positioning note

This document is written from the perspective of Microsoft Azure, Cloud Scale Analytics, and CSA Loom. Any description of third-party or competing products, services, pricing, or capabilities is derived from publicly available documentation and sources believed accurate at the time of writing, and is provided for general comparison only. We do not claim expertise in, or authority over, any non-Microsoft product or service; the respective vendor's official documentation is the authoritative source for their offerings, which may change over time. Nothing here is intended to disparage any vendor — where a competing product has genuine advantages, we aim to note them honestly. Verify all third-party details against the vendor's current official documentation before making decisions.

🚀 Getting Started

For New Projects

  1. Define your requirements: Data volume, latency, use cases
  2. Start with the medallion architecture: Bronze (raw) → Silver (cleansed) → Gold (curated)
  3. Choose your primary compute: Synapse for unified analytics, Databricks for ML-heavy workloads
  4. Implement governance early: Unity Catalog or Azure Purview

For Migrations

  1. Assess current state: Data sources, transformations, reports
  2. Plan incremental migration: Start with non-critical workloads
  3. Leverage compatibility: T-SQL for SQL Server migrations, Spark for Hadoop
  4. Validate performance: Benchmark against existing system
